FIELD

The present disclosure belongs to the technical field of clothingtreatment, and specifically provides an air washing device for aclothing treatment apparatus, and a clothing treatment apparatus.

BACKGROUND

A clothing treatment apparatus is an apparatus capable of washing,drying, sterilizing and/or deodorizing clothing. With the continuousimprovement of production level and ongoing growth of users' needs,users have raised higher and higher requirements on the clothingtreatment apparatus.

In the prior art, taking a washing machine as an example, the clothingis generally washed by water. The washing process is accompanied bymechanical rotation, so that stains on the clothing are washed away.However, this washing method has a limitation in that if a large amountof water is injected into a washing drum at the beginning, the stains ona surface of the clothing will directly enter a lining of the clothingin a state where a washing liquid is not completely dissolved, so thatmore time, water amount, washing liquid and mechanical action arerequired for washing the clothing clean in the subsequent washingprocess, thus resulting in a poor washing effect. In existing clothingtreatment apparatuses, other functions are often added on the basis of awashing machine, such as adding a drying function to become awashing-drying integrated machine, etc. Such an improvement does notsignificantly improve the washing effect of the washing machine.Moreover, current washing machines still cannot achieve in-depthtreatment of clothing made of special materials, such as cashmere, wooland other materials. If the traditional washing by water is used, it ishighly possible that fiber structures of the clothing will be damaged,which will cause a very big limitation on an applicable range of theclothing of the washing machine.

Accordingly, there is a need in the art for a new air washing device fora clothing treatment apparatus, and a corresponding clothing treatmentapparatus, so as to solve the above problems.

In view of the problems of poor washing effect and very limitedapplicable range of clothing of existing clothing treatment apparatuseswith a washing function, the present disclosure provides an air washingdevice for a clothing treatment apparatus, and a clothing treatmentapparatus, aiming at improving the washing effect of the clothingtreatment apparatuses with the washing function on the clothing,increasing the applicable range of the clothing, meeting user'srequirements on use, and thereby improving the user experience.

First Technical Solution

The clothing treatment apparatus of the present disclosure includes aclothing treatment drum. As shown in FIG. 1, the air washing deviceincludes a water supply valve 1, a connection mechanism, and anatomization generator 2. The water supply valve 1 is connected with theatomization generator 2 through the connection mechanism. The connectionmechanism is provided with a one-way check structure, and the one-waycheck structure is arranged to be isolated from the atmosphere when thewater supply valve 1 is opened and to communicate with the atmospherewhen the water supply valve 1 is closed. An outlet of the atomizationgenerator 2 is arranged facing an inner cavity of the clothing treatmentdrum. The connection mechanism may be a separate connection pipe, or itmay be a water delivery mechanism of the clothing treatment apparatusitself (for example, a dispensing device 5 of the drum washing machine).Those skilled in the art may flexibly set the specific structure of theconnection mechanism in practical applications, as long as the water canbe contained by the connection mechanism. The atomization generator 2may be an ultrasonic atomization generator or a compressed atomizationgenerator. Those skilled in the art may flexibly set the specificstructure of the atomization generator 2 in practical applications, aslong as the atomization generator 2 can convert the water in theconnection mechanism into atomized water droplets when the one-way checkstructure communicates with the atmosphere so as to perform atomized airwashing of the clothing. In addition, a one-way check valve 7 may beused as the one-way check structure, such as the one-way check valve 7in the patent No. 201721853840.8. The principle of the one-way checkvalve 7 belongs to the prior art, so it will not be described in detailherein. Of course, in the present disclosure, other one-way checkstructures may also be used. For example, the one-way check structureincludes a cylinder, a movable block arranged in the cylinder, and aspring connected between the cylinder and the movable block. The movableblock divides an internal cavity of the cylinder into two parts. A toppart of the cylinder is provided with an air inlet, a bottom part of thecylinder is provided with a water inlet, and a middle part of thecylinder is provided with an outlet. The spring allows the movable blockto move between a top limit position, a middle position and a bottomlimit position. When the spring is in its natural state, it enables themovable block to be maintained at the bottom limit position. At thistime, the air inlet communicates with the outlet, and the water inlet isisolated from the outlet by the movable block, so as to realize thecommunication between the one-way check structure and the atmosphere.When water inflows from the water inlet, the water pressure moves themovable block to the top limit position against the force of the spring,so that the water inlet communicates with the outlet, and that the airinlet is isolated from the outlet by the movable block. The one-waycheck structure allows water to pass through and be isolated from theatmosphere. It should be noted that the above-mentioned top part andbottom part are defined relative to the cylinder, and they do notconstitute restrictions to the direction and specific positions ofarranging the one-way check structure. Alternatively, the one-way checkstructure may also be a plug structure. Specifically, an opening isprovided at the highest point of the connection mechanism, and a plug isprovided at the opening. When water inflows from the water supply valve1, the opening is closed by the plug, and when the water supply valve 1is closed, the plug is removed and the opening communicates with theatmosphere, so that the water in the connection mechanism is sprayedfrom the outlet of the atomization generator 2. Those skilled in the artmay flexibly set the specific structure of the one-way check structurein practical applications, as long as the one-way check structure can beisolated from the atmosphere when the water supply valve 1 is opened andcan communicate with the atmosphere when the water supply valve 1 isclosed.

It should be noted that by using the one-way check structure, thepresent disclosure enables the atomization generator 2 to smoothlygenerate atomized water droplets. This is because when the water supplyvalve 1 is always open, it is very difficult for the atomizationgenerator 2 to form atomized water droplets under the action of waterpressure. Therefore, the water supply valve 1 can be opened toaccumulate water in the connection mechanism, and then the water supplyvalve 1 can be closed. At this time, the water in the connectionmechanism can be sprayed onto the clothing in the form of atomized waterdroplets from the atomization generator 2 according to the principle ofatmospheric communication, so as to ensure that the atomizationgenerator 2 can perform atomized air washing of the clothing.

In addition, it should be noted that the clothing treatment apparatus ofthe present disclosure may be a drum washing machine, a pulsator washingmachine, a washing-drying integrated machine, a clothing care machine,etc., and those skilled in the art may flexibly set the applicationobjects of the technical solutions of the present disclosure. Suchadjustments and changes to the application objects do not deviate fromthe principle of the present disclosure, and should be defined withinthe scope of protection of the present disclosure. The technicalsolutions of the present disclosure will be further explained below inconjunction with a drum washing machine.

Specifically, as shown in FIG. 2, the drum washing machine of thepresent disclosure includes a cabinet, a drum 3 arranged in the cabinet,and a window gasket 4 connected between an outer cylinder of the drum 3and the cabinet. The atomization generator 2 is preferably arranged onthe window gasket 4, and an outlet of the atomization generator 2 isarranged facing an inner cavity of the drum 3. Of course, theatomization generator 2 may also be arranged on the outer cylinder ofthe drum 3, as long as it can spray atomized water droplets onto theclothing in an inner cylinder of the drum 3 so as to perform atomizedair washing. In addition, the drum washing machine also includes adispensing device 5 arranged on the cabinet. The dispensing device 5includes a clothing treatment agent dispensing cavity, and a water boxarranged on a top of the clothing treatment agent dispensing cavity. Awater delivery channel 51 is formed in the water box to deliver water. Awater inlet end of the water delivery channel 51 is connected to thewater supply valve 1 arranged outside of the dispensing device 5, and awater outlet end of the water delivery channel 51 is connected to theatomization generator 2. The water outlet end of the water deliverychannel 51 may be directly connected to the atomization generator 2through a pipe, or a water tank 6 may also be arranged between the waterdelivery channel 51 and the atomization generator 2. That is, the wateroutlet end of the water delivery channel 51 is first connected to thewater tank 6 through a pipe, and the water tank 6 is then connected tothe atomization generator 2 through another pipe. The water tank 6 has afunction of accumulating water, and the one-way check valve 7 isarranged on the water delivery channel 51. For example, the one-waycheck valve 7 may be arranged close to the water inlet end of the waterdelivery channel 51. Of course, the one-way check valve 7 may also bearranged at other positions of the water delivery channel 51, and thoseskilled in the art may flexibly set the position where the one-way checkvalve 7 is arranged on the water delivery channel 51 in practicalapplications. Such adjustments and changes to the position where theone-way check valve 7 is arranged do not constitute restrictions to thepresent disclosure, and should be defined within the scope of protectionof the present disclosure.

Preferably, the position where the one-way check valve 7 is arranged isat a different height from the position where the outlet of theatomization generator 2 is arranged, that is, when the one-way checkvalve 7 communicates with the atmosphere, a certain liquid leveldifference can be formed between the one-way check valve 7 and theoutlet of the atomization generator 2, so that the water accumulated inthe water delivery channel 51 can be sprayed onto the clothing moreeasily in the form of atomized water droplets through the atomizationgenerator 2. Since the position where the dispensing device 5 isarranged is generally higher than the position where the drum 3 isarranged in the drum washing machine, it is more preferable to set theposition where the one-way check valve 7 is arranged to be higher thanthe position where the outlet of the atomization generator 2 isarranged, thereby making full use of the original structure of the drumwashing machine.

Second Technical Solution

As shown in FIGS. 3 and 4, the drum washing machine of the presentdisclosure includes a cabinet, a drum 1, a water supply valve 2, adispensing device 3, and an atomization generator 4. The dispensingdevice 3 includes a water delivery channel 31, through which the watersupply valve 2 is connected to the atomization generator 4. An outlet ofthe atomization generator 4 is arranged facing an inner cavity of thedrum 1. The water delivery channel 31 is provided with a water diversionstructure 5, which is arranged to be able to communicate with theatmosphere. The water diversion structure 5 may be a water diversionport provided on the water delivery channel 31, or a water diversionpipe provided on the water delivery channel 31. The structure of thewater diversion port or the water diversion pipe can realize waterdiversion of the water diversion channel 31. Of course, the waterdiversion structure 5 may also be a plug structure provided on the waterdelivery channel 31. Specifically, when the water diversion structure 5is the plug structure, an opening is provided on the water deliverychannel 31, and a plug is provided at the opening. When water inflowsfrom the water supply valve 2, the opening is closed by the plug, andwhen the water supply valve 2 is closed, the plug is removed and theopening communicates with the atmosphere, so that a part of the water inthe water delivery channel 31 is diverted from the opening, and theother part of the water is sprayed from the outlet of the atomizationgenerator 4. In addition, the atomization generator 4 may be arranged ona window gasket 6 of the drum 1. The window gasket 6 is connectedbetween the cabinet and the drum 1, and a nozzle of the atomizationgenerator 4 is arranged facing the inner cavity of the drum 1. Ofcourse, the atomization generator 4 may also be arranged on the outercylinder of the drum 1, as long as it can spray atomized water dropletsonto the clothing in the inner cylinder of the drum 1 to performatomized air washing. The atomization generator 4 may be an ultrasonicatomization generator or a compressed atomization generator. Thoseskilled in the art may flexibly set the specific structure of theatomization generator 4 in practical applications, as long as theatomization generator 4 can convert the water in the water deliverychannel 31 into atomized water droplets when the water diversionstructure 5 communicates with the atmosphere so as to perform atomizedair washing of the clothing.

It should be noted that by using the water diversion structure 5, thepresent disclosure enables the atomization generator 4 to smoothlygenerate atomized water droplets. This is because when the water supplyvalve 2 is always open, it is very difficult for the atomizationgenerator 4 to form atomized water droplets under the action of waterpressure. Therefore, the water supply valve 2 can be opened toaccumulate water in the water delivery channel 31, and then the watersupply valve 2 can be closed. At this time, the water in the waterdelivery channel 31 can be sprayed onto the clothing in the form ofatomized water droplets from the atomization generator 4 according tothe principle of atmospheric communication, so as to ensure that theatomization generator 4 can perform atomized air washing of theclothing.

In addition, it should also be noted that in the present disclosure, awater inlet end of the water delivery channel 31 is connected to thewater supply valve 2 arranged outside of the dispensing device 3, and awater outlet end of the water delivery channel 31 is connected to theatomization generator 4. The water outlet end of the water deliverychannel 31 may be directly connected to the atomization generator 4through a pipe, or a water tank 7 (the structure as shown in FIG. 4) mayalso be arranged between the water delivery channel 31 and theatomization generator 4. That is, the water outlet end of the waterdelivery channel 31 is first connected to the water tank 7 through apipe, and the water tank 7 is then connected to the atomizationgenerator 4 through another pipe. The water tank 7 has a function ofaccumulating water. Those skilled in the art may flexibly set the way inwhich the water delivery channel 31 and the atomization generator 4 areconnected. Such adjustments and changes to the way of connection do notconstitute restrictions to the present disclosure, and should be definedwithin the scope of protection of the present disclosure.

In a possible situation, the water diversion structure 5 is a waterdiversion port provided on the water delivery channel 31. The waterdiversion port may be directly connected to the drum 1 through acommunication structure (such as a pipe) to inject water into the drum1, or the drum washing machine has another component that requireswater/accumulates water. Then, the water diversion port is connectedwith this component through a communication structure (such as a pipe)to inject water into this component. For another example, the dispensingdevice 3 further includes a clothing treatment agent dispensing box, andthe water diversion port is arranged above the clothing treatment agentdispensing box. An upper part of the clothing treatment agent dispensingbox may have an opening structure, and the water diversion port isaligned with the opening structure. When the water supply valve 2 isopened, water enters the water delivery channel 31, flows out of thewater diversion port, enters the clothing treatment agent dispensing boxthrough the opening structure for dilution of the clothing treatmentagent, and finally flows into the drum 1. When the water supply valve 2is closed, the atomization generator 4 is opened, and since the waterdiversion port communicates with the atmosphere, a part of the water inthe water delivery channel 31 flows into the clothing treatment agentdispensing box through the water diversion port, and the other part ofthe water forms atomized water droplets under the action of theatomization generator 4, which are then sprayed onto the clothing.Moreover, under the action of the atmosphere, if the atomizationgenerator 4 is always turned on, the water in the water delivery channel31 can be fully drained to avoid residual water and growth of bacteria.In this embodiment, the number of water diversion ports may be one orplural. Those skilled in the art may flexibly set the number anddistribution of the water diversion ports in practical applications, aslong as the diversion of water and the communication with the atmospherecan be realized through the water diversion ports.

In another possible situation, the water diversion structure 5 is awater diversion pipe provided on the water delivery channel 31. Thewater diversion pipe may be directly connected to the drum 1 through acommunication structure (such as a pipe) to inject water into the drum1, or the drum washing machine has another component that requireswater/accumulates water. Then, the water diversion pipe is connectedwith this component through a communication structure (such as a pipe)to inject water into this component. For another example, the dispensingdevice 3 further includes a clothing treatment agent dispensing box, andan outlet of the water diversion pipe is arranged above the clothingtreatment agent dispensing box or extends into the clothing treatmentagent dispensing box. When the outlet of the water diversion pipe isarranged above the clothing treatment agent dispensing box, an upperpart of the clothing treatment agent dispensing box may have an openingstructure, and the outlet of the water diversion pipe is aligned withthe opening structure. When the outlet of the water diversion pipeextends into the clothing treatment agent dispensing box, it is onlyrequired to provide an opening on the clothing treatment agentdispensing box for docking with the outlet of the water diversion pipe.When the water supply valve 2 is opened, water enters the water deliverychannel 31, flows out of the outlet of the water diversion pipe, thenenters the clothing treatment agent dispensing box for dilution of theclothing treatment agent, and finally flows into the drum 1. When thewater supply valve 2 is closed, the atomization generator 4 is opened,and since the water diversion pipe communicates with the atmosphere, apart of the water in the water delivery channel 31 flows into theclothing treatment agent dispensing box through the outlet of the waterdiversion pipe, and the other part of the water forms atomized waterdroplets under the action of the atomization generator 4, which are thensprayed onto the clothing. Moreover, under the action of the atmosphere,if the atomization generator 4 is always turned on, the water in thewater delivery channel 31 can be fully drained to avoid residual waterand growth of bacteria. In this embodiment, the number of waterdiversion pipes may be one or plural. Those skilled in the art mayflexibly set the number and distribution of the water diversion pipes inpractical applications, as long as the diversion of water and thecommunication with the atmosphere can be realized through the waterdiversion pipes.

Preferably, the position where the water diversion structure 5 isarranged is at a different height from the position where the outlet ofthe atomization generator 4 is arranged, that is, when the waterdiversion structure 5 communicates with the atmosphere, a certain liquidlevel difference can be formed between the water diversion structure 5and the outlet of the atomization generator 4, so that the wateraccumulated in the water delivery channel 31 can be sprayed onto theclothing more easily in the form of atomized water droplets through theatomization generator 4. Since the position where the dispensing device3 is arranged is generally higher than the position where the drum 1 isarranged in the drum washing machine, it is more preferable to set theposition where the water diversion structure 5 is arranged to be higherthan the position where the outlet of the atomization generator 4 isarranged, thereby making full use of the original structure of the drumwashing machine.

Hitherto, the technical solutions of the present disclosure have beendescribed in conjunction with the preferred embodiments shown in theaccompanying drawings, but it is easily understood by those skilled inthe art that the scope of protection of the present disclosure isobviously not limited to these specific embodiments. Without departingfrom the principles of the present disclosure, those skilled in the artcan make equivalent changes or replacements to relevant technicalfeatures, and all the technical solutions after these changes orreplacements will fall within the scope of protection of the presentdisclosure.
